HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 403,474, dated May 14, 1889.

Application filed October 6, 1888. Serial No. 287,408- (No model.)

To all whom it may concern.-

Be it known that I, JONATHAN JOHNSON, a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Heating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to IO which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

r 5 This invention relates to an improvement in heating apparatus, consisting of an arrangement for heating purposes, in which gas or oil is used for fuel, the apparatus forming an odorless radiator for both heating and ventilating.

It is constructed of a base-plate with leg-supports, having attached to the under side of the base-plate drop-arms or yokes, which carry the gas or oil pipe. This pipe has a series of burners connected, which are brough t 2 5 to the center of vertical radiator-pipes when the burners are lighted, the flame entering said pipes. The gas or oil pipe is turned so as to bring said burners outside the radiating-pipes, in order to bring them into a con- 0 venient position for lighting, and when gas is used as fuel it will not enter the radiatingpipes until lighted, and the gas-pipe is turned to the working position under the radiatingpipes. If lighted when the burners are upright, the gas will enter the radiator-pipes, and, mixing with the air therein, become an element for explosion, which explosion will extinguish the flame, making it very difficult to put a radiator at work. The top of the radiator is arranged with a tight chamber, the vertical pipes being securely fitted in the under side of said chamber. 011 the upper and back part of said chamber is fitted a smoke-flue for connecting a pipe to carry off the odor to the chimney. The vertical pipes are open from base to top, which admits air for combustion and also furnishes ventilation to the room.

In the drawings illustrating this invention,

Figure l. is a vertical longitudinal section through one series of radiating-pipes and their supports, showing the burners in posi tion for heating the same. Fig. 2 is a transverse Vertical section illustrating the method of securing the base, radiating-pipes, and chamber, which receive the products of combustion together. Fig. 3 shows a modification of the means employed for securing the operating-pipes in place.

In the figures, A represents the base-plate provided with suitable feet to sustain it at a proper height from the floor. This plate is pierced with one or more rows of holes to receive the lower ends of the series of radiating-pipes a a, which are inserted therein, being prevented from passing downward through the same by the shouldered projections or washers a a, preferably cast with the plate; or the washer may be attached to the pipe and enter the hole in the plate, a nut, a, being screwed on the lower end of the pipe, beneath the plate, to secure the parts firmly together, as shown in Fig. 3 of the drawings. The upper ends of the radiatingpipes a pass through a row of holes in the plate 13 corresponding with those in the baseplate, the two plates being retained in their proper position with relation to each other and the radiating-pipes by the rods 1) b, which pass through said plates, and are provided at top and bottom with screw-threads and nuts that, when screwed up against the plates, hold all the parts firmly in position. Above this plate B, and secured thereto in any suitable manner, is the canopy or top 0, leaving between it and said plate a chamber, D. The sides and top of this chamber form radiating-surfaces, and the chamber itself receives all the waste products from the combustion of the fuel, which products pass upward 0 through the radiating-pipes into said chamber and are conducted therefrom through the pipe Z), attached at one side of the chamber to a chimney or other means of conveying away said waste products.

Attached to the downwardly projecting flange of thebase A, at each end, are the yokes or pipe-supports o 0. These yokes or pipe supports 0 c are made in separate pieces secured to the flange by screws, so that either roe may be removed without disturbing the others or the pipe which they may carry. Supported by these yokes are the pipes E, connected at one end by a turning joint with afuel-supply pipe, F, and provided at the other with a handle, d, by means of which said pipe E may burners are provided with suitable tips for the same, preferably gas and air mixed, producing the blue flame of a Bunsen burner.

As heretofore stated, if the pipe E were stationary and the burners each opening into the lower end of a radiating-pipe, the flow of gas before it was lighted mixing with the air would form an explosive compound, rendering it not only diflicult, but dangerous, to put the apparatus in action; but by providing means for turning the supply-pipe and with it the burners, so that their tips shall be outside the radiating-pipes, any gas which may escape before lighting mingles with the air of the room and is so diluted as to render it harmless. When oil is used, the turning of the supply-pipe and burners brings the latter.

into a position where they can be readily trimmed and lighted, and when turned back into place beneath the radiating-pipes said pipes act as chimneys to give a good supply of air -to the burner, insuring perfect combustion, while any odor arising from the oil is carried oif through said radiating-pipes.

and the chamber D into the flue or chimney with which the latter is connected.

connecting the pipes and plates the rods 1) are dispensed with, the radiating-pipes forming a firm connection between the two plates.

Having thus described my invention, I claim as new and desire to secure by Letters Patent the following:

1. Asan improvement in heating apparatus, the combination of a suitable base, the rows of vertical radiating-pipes open at both ends, the chamber into which the upper ends of the radiating-pipes open, and the rotating fuel-supply pipes provided with a burner for each radiating-pipe placed horizontally within the base and adapted to be rotated upon its axis to carry the burners away from beneath the open lower ends of the radiating-pipes, substantially as and for the purpose set forth.

2. As an improvement in heating apparatus, the combination, with the base, the radiating-pipes supported thereon, and the horizontally-placed fuel-supply pipes rotating upon their axes and provided with a burner for each radiating-pipe, of the supports 0 c, secured within and to the base, forming bearings upon which the supply-pipes are rotated by means of suitable handles attached to the pipe, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JONATHAN JOHNSON.
